The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. The value of I B should not exceed mA. Of the above types common emitter type is the popular and mostly trannsistor configuration.

What is Web Browser. When this trabsistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

BC is a NPN transistor hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and will be closed Forward biased when a signal is provided to base pin. As mentioned the biasing current should maximum of 5mA. It has a maximum current gain of BC has a gain value of tothis value determines the amplification capacity of the transistor. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base.


TL — Programmable Reference Voltage.

Amplifier modules like Audio amplifiers, signal Amplifier etc. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. It can amplify power, voltage and current at different configurations. Arduino based GPS receiver. BC is mainly used for amplification and switching purposes. The voltage divider is the commonly used biasing mode. A transistor, stands for transfer of resistance, is commonly used to amplify current.

Complete Technical Details can be found at the datasheet give at the end of this page. Choosing Motor For Robots.

Skip to main content. As discussed a transistor will act as an Open datashfet during Forward Bias and as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin.

BC Datasheet, PDF – Alldatasheet

Choosing Battery for Robots. The input signal at base is amplified and taken at the emitter. If you are designing a Trannsistor or Perf board with this component then the following picture from the Datasheet will be useful to know its tranaistor type and dimensions. Its equivalent transistors are BC and BC To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Virgin Galactic — Commercial Space Flight. Interface SD Card with Arduino.


A Transistors acts as datasheeet Amplifier when operating in Active Region. BC is used in common emitter configuration for amplifiers. For amplification applications, the transistor is biased such that it is partly on for all input conditions.

In the absence of base signal, it gets completely off. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. This high-density System-in-Package SiP integrates controller, power switches, and support components.

SPI Module of Arduino. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. Interface GPS with Arduino. Submitted by admin on 30 August The value of this resistor R B can be calculated using below formulae.

BC is an NPN bi-polar junction transistor.

When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. This is known as the biasing.
